The GTX 690’s list of accomplishments is impressive to say the least but none of these milestones can measure up to the performance numbers it achieves. By leveraging the Kepler architecture’s inherent efficiency, NVIDIA was able to combine two fully enabled GK104 cores onto a single PCB and has set bar so high, AMD will have a hard time regaining the performance lead. To hit optimal power consumption numbers, the Base Clock of both cores was reduced but due to Boost clocks and the PLX chip's low latency interface, the real world difference between the GTX 690 and a pair of GTX 680s in SLI is nonexistent. Indeed, the GTX 690 represents a quantum leap over the last generation of dual GPU cards and is so powerful that it would be a complete waste to buy for resolution at or above 2560 x 1440.
